JOHN S. BLAKELY, OF KANSAS CITY, MISSOURI.

GRAIN-METER.

SPECIFICATION forming part of Letters Patent No. 742,959, dated November3, 1903.

Application filed January 19 1903- Serial No. 139,517. (No model.)

To all whom it may concern.-

Be it known that I, JOHN S. BLAKELY, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Grain-Meters, ofwhich the following is a specification.

My invention relates to improvements in grain-meters; and my object isto provide a machine of this character which will accurately and rapidlyweigh the grain as it is delivered from a separator, bin, elevator,cornsheller, or any other source of supply and discharge it into a bin,wagon-box, or other receptacle provided for that purpose.

The invention may also be said to consist in the novel arrangementandcombination of parts hereinafter described, and more particularlypointed out in the claims.

In the accompanying drawings, which illustrate the invention, Figure 1represents a side elevation of my improved grain-meter so? cured uponthe'top of a separator. Fig. 2 is a plan View of the same. Fig. 3 is avertical section of the hopper, taken on line III III of Fig. 2. Fig. 4is a vertical sectional view of the segmental housing, taken on line IVIV of Fig. 1.

In the drawings, 1 indicates the upper portion of a separator, providedwith the usual or any preferred grain-elevator 2, having adischarge-spout 3 at its upper end.

4. indicates the improved hopper, which is located vertically belowspout 3 and is divided into four compartments 5 by radial partitions 6,which are secured at their opposite sides to disks 7, forming the sidesof the hopper and provided at their outer sides with rings 7, havingflat sides which fit against the disks and rounded outer sides which addto their rigidity and prevent them and the disks from bending under thestrain to which they are subjected, said rings having fourequally-spaced outwardly-extending stop-pins 7".

Hopper 4 is mounted upon a centrally-located transverse shaft 8,journaled at its opposite ends in bearings 9, formed integral with theouter ends of brackets 10, secured to a transverse plate 11, which isremovably' fastened to the down-spout of the elevator by clamps andbolts 12 13, respectively. The

front portion of the hopper is inclosed by a snugly-fitting segmentalhousing 14, provided at its opposite sides with marginal flanges 15 andat its lower portion with a spout 16, carrying a collar 17, having twooppositely-disposed arms 18, provided with pins 19, adapted to receiveaswivel-spout 20, through which grain from the meter may be dischargedinto a wagon-box or other receptacle. The hopper is normally held in theposition shown in Fig. 1 by a weigh-beam 21, fulcrumed near its rearbifurcated end 22 upon a knife-edge bearing 23 and provided at itsforward graduated portion with a poise 24:, adapted to be socured at anypoint thereon by a set-screw 25. The upward movementof the bifurcatedend 22 is limited by contacting with pins 26, projecting from theopposite sides of the segmental housing, beyond which said ends projectinto the path of pins '7", so the latter will contact therewith and holdthe hopper in the above-described position until itsupper forwardcompartment receives sufficient grain to overbalance poise 24., when thebifurcated end of the weigh-beam will be forced out of the path of thecontacting pins 7 as the hopper is rotated by its charge of grain. Asthe contacting pins 7 pass free of the bifurcated end 22 the latter isinstantly reelevated in contact with pins 26-by poise 2a in order to bein position to intercept the succeeding stoppin 7*, and thus prevent thehopper from completing more than one-fourth of a revolution, which isample movement for the discharge of its load into spout l6, and to stopit in position to receive another charge from spout 3. This operation isrepeated until the elevator is stopped. The opposite ends of knife-edgebearing 23 are secured in jaws" 27, formed at the upper end of a bracket28, secured upon the top of the separator and'provided with a support 29for holding the segmental housing in position.

From the above description it is apparent that I have produced agrain-meter which is simple in construction and thoroughly eifective forthe purpose intended.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a grain-meter, a hopper comprising two disks forming the sidesthereof, radial par- ICO titions secured at their opposite sides to thedisks, a transverse shaft extending through the central portion of thehopper and suitably journaled at its outer ends, rings secured to theouter sides of the hopper, stoppins projecting, therefrom, and a fulcrumweigh-beam having one of its ends arranged in the path of the stop-pinsand provided at its opposite end with a poise, substantially asdescribed.

2. Ahopper divided into a plurality of compartments for receivingsuccessive charges of grain, a central transverse shaft upon which saidhopper is mounted, a pair of triangular brackets arranged at theopposite sides of the hopper, bearings formed integral with the outerends of the brackets to receive the opposite ends of the transverseshaft, a plate to which the opposite ends of the brackets are secured,clamps for securing the plate to one of the spouts of the elevator, andmeans for weighing the grain in the hopper, substantially as shown anddescribed.

3. In a grain-meter, the combination of an elevatorhaving adischarge-spout,with ajournaled hopper adapted to receive the graindischarged from said spout, a housing inclosing the front end of thehopper and arranged eccentrically therewith and extending downwardlyfrom a point adjacent to the lower terminal of the spout to a suitabledistance below the hopper, marginal flanges forming the sides of saidhousing and which are eccentric with and overlap the sides of thehopper, and a spout secured to the lower end of the housing,substantially as shown and described.

4. In a grain-meter, a journaled hopper, a housing inclosing the frontend of said hopper, a spout secured to the lower end of the housing, acollar embracing the spout, a pair of oppositely-disposed arms securedto the collar, pins secured to the said arms, and a spout which isswiveled to said pins, substantially as described.

5. In a grain-meter, a journaled hopper divided into a plurality ofcompartments, rings secured to the opposite sides of said hopper,stop-pins projecting from the rings and which are equal in number to thecompartments of the hopper, a housing inclosing the front end of thehopper, a pair of pins projecting from the opposite sides of thehousing, a weighbeam having a bifurcated end adapted to engage the pinson the housing and rings, a bracket provided with upwardly disposed jawsbetween which the weigh-beam is' pivoted, and a support projecting fromthe rear end of the bracket for the purpose of holding the housing.

In testimony whereof I affix my signature in the presence of twowitnesses.

JOHN S. BLAKELY.
